I am a VERY new user and i need a formula that when the opportunity is saved, it will calculate the total price of items with a specific word in the product code or description. Can anyone help with that?

I have postal codes going into a text box and it keeps adding ".0000" to the end of all of the numeric codes. How do I stop this and have it be only whole numbers or alpha-numeric characters?
